This paper presents the findings of an experimental program aimed at investigating the strain distribution between Carbon Fiber Reinforced Polymer (CFRP) sheets and concrete. CFRP is used as externally bonded reinforcement for concrete structures to improve flexure and shear strength and confinement of concrete. The effects of bonded length, concrete strength, and number of plies (or stiffness)...
ABSTRACT: This paper explores the behavior of infill masonry structures strengthened with a new type of Fiber Reinforced Polymer (FRP) strengthening system with high fracture strain know as PET (Polyethylene Teraphthalate) and a new near-surface mounted (NSM) Carbon fiber strengthening system using a cementitious material as the adhesive as compared to a Glass Fiber (GFRP) strengthening system ...
this paper presents the results of analytical studies concerning the flexuralstrengthening of reinforced concrete beams by external bonding of high-strength lightweightcarbon fiber reinforced plastic (cfrp) plates to tension face of the beam. three groups of beamswere tested analytically and compared with existing experimental results. results of the numericalanalyses showed that, although addi...
the current study is focused on strengthening of reinforced concrete (rc) beams using cfrp straps installed in pre-cut grooves. the method which is referred as near surface mounted (nsm) benefits considerable advantages in comparison with the conventional externally bonded reinforcement (ebr) method and provides better normal and shear stress transfer between the frp and concrete substrate. the...
. this paper presents the results of an experimental investigation on shear strength enhancement of reinforced concrete deep beams externally reinforced with fiber reinforced polymer (frp) composites. a total of six deep beam specimens of two different classes, as-built (unstrengthened) and retrofitted were tested in the experimental evaluation program. two composite systems namely carbon/epoxy...
To explore the possibilities and benefits of using CFRP (Carbon Fibre Reinforced Polymers) in strengthening RC building columns, quasi-static tests (compression bending) were carried out at Institute Earthquake Engineering Seismology - IZIIS, Skopje by variation concrete class, reinforcement percentage various technologies. Some recommendations outcomes regarding approach, technology conclusion...
Selecting appropriate bonding technique is crucial for strengthening and repairing concrete structures as different bonding techniques have different performances. A state-of–the-art review of different bonding techniques that is epoxy bonding technique, prestressed strengthening technique, unbonded anchored technique/mechanically fastened technique using CFRP is dealt and the corresponding adv...
